5×2 patch board

Posted: May 7th, 2010, 3:00pm MDT by Mike Szczys

Sometimes we want to sit on the back porch, crack a beer, and do some prototyping. Other times we’d like to do the same but on the couch in the livingroom. To that end we added a 5×2 pin to 10×1 pin patch board to our solderless breadboard. The 5×2 pin form factor is pretty [...]
Reuse that PDA as a WRT terminal

[Michu] used his old Palm IIIc to make a serial interface for his OpenWRT router. It’s a matter of cracking open both the router and the Palm device, then connecting the TTL lines from the router to the MAX 3386e level converter chip inside the Palm. From there, Pocketterm can connect to the router’s serial [...]
Toner transfer explained step-by-step

[Tanjent] send us a link to his tutorial on the toner transfer process for fabricating circuit boards. We’ve seen a lot of these in the past, but we liked how his is straight to the point while also sharing several tips and options along the way. Notably, he ”tints” the copper clad before trying to [...]
Hand made manipulator arm

[Anton] spent 100 hours building this manipulator arm by hand. He made the parts by drawing them on styrene and [...]
Peltier cooler based cloud chamber

Posted: May 7th, 2010, 7:13am MDT by Caleb Kraft

[Rich] shares with us his build of a Peltier cooler based cloud chamber. This nifty little tool allows him to see the paths that radioactive particles take through alcohol vapor. The system he has come up with is fairly cheap at roughly $100. He’s using Peltier coolers from computers and a cheap ATX power supply. [...]
